The short version

  • Each has a real cost: Pontoon there is no hosted commercial edition, so adopting it means running Django, PostgreSQL and a task queue yourself and keeping them patched.; Reverso there is no meaningful volume-priced developer API, so it is not a fit for embedding translation into an application the way Google, Microsoft or Amazon’s APIs are.
  • They diverge on capability: Pontoon covers Repository sync, Reverso covers Context search.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Pontoon

  • There is no hosted commercial edition, so adopting it means running Django, PostgreSQL and a task queue yourself and keeping them patched.
  • No vendor support and no service level agreement exist, so an outage during a release freeze is your engineering problem alone.
  • The roadmap serves Mozilla localisation needs first, and features outside that scope are unlikely to be built for you.
  • Format coverage is narrow next to commercial systems: it is strong on PO and Fluent, weak on document formats such as InDesign or complex XML.
  • Because you host it, security and compliance evidence such as an external audit report does not exist, so any assurance your customers need has to be produced by your own team.

Reverso

  • There is no meaningful volume-priced developer API, so it is not a fit for embedding translation into an application the way Google, Microsoft or Amazon’s APIs are.
  • Document translation is capped by annual word count even on paid tiers, ruling it out for high-volume automated translation workloads.
  • It has no on-premises or enterprise-scale deployment option, unlike Systran, so organisations with data residency requirements cannot use it for sensitive content.
  • The free tier is ad-supported and limited on document translation, pushing regular users toward Premium fairly quickly.
  • Context search quality depends on the size and domain coverage of its bilingual corpus, which can thin out for less common language pairs or highly technical terminology.

Answered from the vendors’ own pages

Pontoon: Is there a paid hosted version?

No. Mozilla runs an instance for its own projects. Anyone else deploys their own.

Reverso: Is Reverso a machine translation API for developers?

No, it is a consumer-facing product with no significant developer API business; Google, Microsoft or Amazon are the appropriate choice for embedding translation into an application.

Pontoon: What does it actually cost?

Server hosting, engineering time to operate it, and whatever machine translation engine you connect. There is no licence fee.

Reverso: What is the context search feature?

It shows real bilingual example sentences from translated documents and subtitles alongside a translation, which is useful for checking natural usage rather than a raw one-line output.

Pontoon: Is it suitable for a commercial product?

Only if you have infrastructure staff and mostly software string formats. Document translation and vendor support are missing.

Reverso: How much document translation do I get on Premium?

50,000 words a year on Premium; the Pro tier raises that to 200,000 words a year with larger file support.
